For Itinerary at least the release branch is using release tarballs rather 
than (latest) Git branches, matching what we have on Flathub. (This does imply 
some manual work at branch time, but at least for me that's more than offset by 
what this saves in catching issues early).

But you are right of course that this is abusing Flatpak a bit as CI. That's 
not ideal but it's just very tempting as it has minimal extra cost (Flatpak 
has to build those dependencies anyway, and Flatpak builds run less often than 
normal CI builds).
